Effect of Salicylic, Humic and Fulvic Acids Application on The Growth, Productivity and Elements Contents of Two Wheat Varieties Grown Under Salt Stress تأثير إضافة أحماض الساليسيليک والهيوميک والفولفيک على النمو والإنتاجية ومحتويات العناصر لصنفين من القمح النامى تحت الاجهاد الملحى

A field experiment was carried out at the farm of El-Nubaria Agricultural Research Station, Behaira Governorate, Agric. Res. Center, and Ministry of Agriculture and land Reclamation, Egypt. During 2016/2017 and 2017/2018 winter seasons to evaluate the effect of salicylic, humic and fulvic acids application on growth, productivity and mineral contents of two wheat (Triticum aestivum L.) varieties grown under salt-affected soil conditions in the Nubaria region. The experimental design was split

Main treatments were two different wheat cultivars (Sids 12 and Sakha 94) while sub-main plot was control, Potassium fulvate as foliar application (1 kg fed -1 ), Salicylic acid as foliar application (1.600 kg fed -1 ), Potassium humate as foliar application (1 kg fed -1 ), Potassium fulvate (1 kg fed -1 ) + Salicylic acid (1.600 kg fed -1 ) + Potassium humate (1 kg fed -1 ) as foliar application, Potassium fulvate as soil application (2 kg fed -1 ), Salicylic acid as soil application (3.200 kg fed -1 ), Potassium humate as soil application (2 kg fed -1 ) and Potassium fulvate (2 kg fed -1 ) + salicylic acid (3.200 kg fed -1 ) + Potassium humate (2 kg fed -1 ) as soil application. The obtained results showed that Potassium fulvate + Salicylic acid + Potassium humate as soil application was significantly superior and had the best means of all Studied traits; namely, plant height, grains weight, weight 1000 grains, grain yield, macronutrients in straw, secondary elements in straw, micronutrients in straw, elements in grains, protein in grains, micronutrients in grains, element in soil, Nutrient Use Efficiency and Agronomic Efficiency compared with the control and with foliar application of organic acid under salinity stress. In addition, results showed that Sids 12 was the best and more tolerant in the most studies traits under salinity stress compared with Sakha 94 cultivar.
